+# MLflow × Crusoe AI
+
+Track LLM experiments on [Crusoe Managed Inference](https://www.crusoe.ai/cloud/managed-inference) using MLflow — log parameters, latency metrics, and model outputs across runs.
+
+## What this does
+
+Runs 3 LLM inference experiments and logs everything to MLflow:
+
+- **Parameters** — model name, temperature, max tokens, prompt
+- **Metrics** — latency, output word count, words per second
+- **Artifacts** — full model response saved per run
+
+## Prerequisites
+
+- Python 3.10+
+- A Crusoe Cloud account → [console.crusoecloud.com](https://console.crusoecloud.com)
+- Inference API key (Intelligence API Keys section under Security)
+
+## Setup
+
+```bash
+pip install -r requirements.txt
+export CRUSOE_API_KEY="your-api-key"
+```
+
+## Run the experiments
+
+```bash
+python train_and_log.py
+```
+
+## View results in MLflow UI
+
+```bash
+mlflow ui
+```
+
+Then open http://localhost:5000 — you'll see all runs under the `crusoe-llm-experiments` experiment with latency and throughput metrics side by side.
+
+## Local testing (no Crusoe account needed)
+
+The script automatically falls back to Groq if `CRUSOE_API_KEY` is not set:
+
+```bash
+pip install langchain-groq
+export GROQ_API_KEY="your-groq-key"  # free at console.groq.com
+python train_and_log.py
+```
+
+## What gets logged per run
+
+| Type | Details |
+|------|---------|
+| Parameters | model, temperature, max_tokens, prompt |
+| Metrics | latency_seconds, output_word_count, words_per_second |
+| Artifacts | full response saved as response.txt |
+
+## Extend it
+
+Add your own prompts to the list in `train_and_log.py`:
+
+```python
+prompts = [
+    ("my_task", "Your prompt here"),
+]
+```
+
+Each entry becomes a named MLflow run, making it easy to compare outputs across models or temperatures.
